Not to fear, Faramir isn’t as big a jerk as most other men are. And Sam’s failure can live to fail another day.
He puts on a bit of a show, but Faramir backs down, letting Frodo and Sam know that he has no intent to take the ring from them. He (somehow) understands the peril and evil of this ring, and that he must not be tempted by it. He praises Frodo, and all of hobbit-kind, for being so strong to carry such a horrible thing. Their homeland must be a wonderful and peaceful place.
They laugh about the esteem of gardeners in the Shire, and all the men in the cave who were alerted to a conflict resolve themselves to assuming that it was just a joke. Faramir bids Frodo and Sam to rest, safely and at peace. No harm will come to them here.
So…Faramir did know about the existence of the ring, eh? He acted so oblivious earlier to what “Isildur’s Bane” could possibly be. Did he really not know? What else could it be? Ah, yes, there was always the possibility that it was a large man in a mask, who once threw Isildur in a prison pit after breaking his back.
And, ultimately, there’s praise for Sam, and the gardening profession, after his latest mistake. That’s a freebie. How long can he keep doing this before it really catches up with him? If this was a world of karma, he’d have accumulated such bad luck that every step would be more likely to make him trip and break every bone in his body. You can’t live that way. He needs to learn this! Now!
No one dies today.
